It is constructed at the same height. Further, in order to obtain a better effect when the blade 1 rotates, the height of the heat dissipation column 32 within the range of the storage space 30 in which the blade 1 rotates is configured to be slightly lower. Therefore, the blade 1 does not collide with the heat radiation column 32, and the slightly higher heat radiation column 32 provided on the outer side can protect the motor 2 and the blade 1.

Radiation-like heat dissipation columns 32B are provided around the space 30B, and the height of the heat dissipation columns 32B located near the storage space 30B is slightly low, so that the blade 1 can rotate on top of it Since the height of the heat dissipation column 32B, which is located away from the space 30B, is rather high, it is configured to protect the blade 1 from rotating therein.

FIG. 7 and FIG. 8 relate to the fourth embodiment of the present invention. Not only the heat dissipation column 32C is similarly provided in the heat dissipation conductor 3C, but a heat dissipation hole 33C is also provided. The heat dissipation holes 33C can improve the effect of heat dissipation, and the heat dissipation holes 33C can have any shape such as a circular hole, a square hole, or a tank hole.

Not only is the heat dissipation conductor 3D provided with a heat dissipation column 32D, but another bottom surface of the heat dissipation column 32D is also provided. The recessed hole 33D is provided in the hole, and the recessed hole 33D is designed so that it can be mixed with the shape of the heat-generating conductor adjacent to the heat-dissipating conductor 3D. Can be intimately blended with, and a better heat dissipation effect can be obtained.

FIG. 10 relates to a sixth embodiment of the present invention. In the heat dissipation conductor 3E, a cutout 33E is provided around the cutout 33E, and a hook or a tenon is locked in the cutout 33E. The heat dissipation conductor 3E is fixed.
